DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example: See also Figure 1-Figure 10 The present invention provides a technical solution: an adjustable infusion stand capable of passively changing medicine solution, comprising a base frame 1, a telescopic column 2 movably installed in the base frame 1, a top plate 3 fixedly installed on the telescopic column 2, a medicine hanging mechanism 6 arranged at equal angles and intervals on the top plate 3, a medicine bottle arranged on the medicine hanging mechanism 6, a first fixed frame 4 and a second fixed frame 5 are respectively fixedly installed on the outer side of the telescopic column 2, a reversing mechanism 23 is arranged in the first fixed frame 4, a first medicine tube 7 and a second medicine tube 8 are inserted in the second fixed frame 5, and the medicine hanging mechanism 6 drives the reversing mechanism 23 to rotate a plurality of second medicine tubes 8 by 90 degrees to communicate with the first medicine tube 7 after the medicine solution in the medicine bottle is infused.

[0022] In this embodiment, the medicine hanging mechanism 6 includes a first fixed box 10, a second fixed box 11, a third fixed box 12 and a sliding box 13. The first fixed box 10, the second fixed box 11 and the third fixed box 12 are all fixedly installed with the bottom end of the top plate 3. The first fixed box 10, the second fixed box 11 and the third fixed box 12 are arranged in sequence, and a hook 14 is movably installed under the first fixed box 10.

[0023] In this embodiment, a first extrusion spring 18 is fixedly installed in the first fixed box 10, the first extrusion spring 18 is connected to the hook 14, a first tooth column 15 is fixedly installed on the side of the hook 14, a first rotating gear 17 is movably installed in the second fixed box 11, a second extrusion spring 19 is fixedly installed in the third fixed box 12, a second tooth column 16 is movably installed through the third fixed box 12, and the second tooth column 16 is fixedly connected to the second extrusion spring 19.

[0024] In this embodiment, the first gear column 15 and the second gear column 16 are both meshed and connected with the first rotating gear 17 , and the first gear column 15 and the second gear column 16 are rotationally symmetrically distributed about the center of the first rotating gear 17 .

[0025] In this embodiment, a piston plate 20 is movably installed in the sliding box 13, the piston plate 20 is fixedly connected to the second gear column 16, the sliding box 13 is set on the first fixed frame 4, and a contact block 21 is fixedly installed in the sliding box 13, and the piston plate 20 is in contact with the contact block 21.

[0026] When the piston plate 20 and the contact block 21 contact each other, it is received that the liquid medicine in the first medicine bottle has been used up.

[0027] The medicine bottle is hung on the hook 14. At the beginning, the medicine bottle will make the hook 14 located at the bottom, so that the first squeezing spring 18 is in a stretched state. As the medicine in the medicine bottle is used, the weight of the medicine bottle begins to gradually decrease, and the first squeezing spring 18 will slowly rise, that is, the hook 14 will slowly rise. When the hook 14 rises, it will drive the first gear column 15 to move up, and the first gear column 15 is meshed and connected with the first rotating gear 17. In this way, the first gear column 15 will drive the second gear column 16 to move down through the first rotating gear 17, and will squeeze the second squeezing spring 19. When the second gear column 16 moves down, the piston plate 20 will move down in the sliding box 13 until the piston plate 20 contacts the contact block 21, that is, all the medicine in the medicine bottle has been used up.

[0028] In this embodiment, the first fixed frame 4 is movably installed with a first gear ring 22 and a rotating column 25, and a motor 24 is fixedly installed. Connecting rods 9 are fixedly installed at equal intervals on the outer side of the top plate 3. The connecting rods 9 are fixedly connected to the first gear ring 22. The bottom ends of several connecting rods 9 pass through the top end of the first fixed frame 4 and are fixedly connected to the top end of the first gear ring 22.

[0029] In this embodiment, the reversing mechanism 23 includes a second gear ring 26, a second rotating gear 27 and a third gear column 28.

The output shaft of the motor 24 is fixedly installed with a push plate 29, and is fixedly connected to the third gear column 28 through the push plate 29. The second gear ring 26 is meshedly connected with the third gear column 28, and the first gear ring 22 is meshedly connected with the second rotating gear 27. When the motor 24 is working, the third gear column 28 will be driven to move through the push plate 29. When the third gear column 28 moves, it will drive the rotating column 25 to rotate through the second gear ring 26, that is, it can drive the second rotating gear 27 to rotate. When the second rotating gear 27 rotates, it will drive the first gear ring 22 to rotate. The first gear ring 22 is fixedly connected to the connecting rod 9, so that the top plate 9 will also rotate.

[0030] A signal receiver is provided on the motor 24, and a signal transmitter is provided on the contact block 21. When the piston plate 20 contacts the contact block 21, the signal generator will transmit a signal, and the signal receiver on the motor 24 will receive the signal and start the motor 24 to work. When the motor 24 works, the push plate 29, the third gear column 28, the second gear ring 26, the rotating column 25, the second rotating gear 27, the first gear ring 22 and the connecting rod 9 are used to drive the top plate 3 to rotate. Each time the motor 24 works, the top plate 3 rotates by 90°, and the sliding box 13 will also slide on the first fixed frame 4.

[0031] In this embodiment, a sliding plate 30 is movably installed on the second fixed frame 5, the second medicine tube 8 is plugged into the sliding plate 30, a sliding block 32 is fixedly installed below the sliding plate 30, and a connecting cavity 31 is opened in the second fixed frame 5, and the first medicine tube 7 and the second medicine tube 8 are connected to each other through the connecting cavity 31.

[0032] When the top plate 3 rotates 90°, the second medicine tube 8 will drive the sliding plate 30 to rotate 90° on the second fixed frame 5 at the same time, so that the next second medicine tube 8 will be reconnected with the connecting cavity 31, so that there is always medicine flowing into the first medicine tube 7, and there is no need to manually replace the medicine bottle. After the medicine in the previous medicine bottle is used up, the next medicine bottle will be passively rotated 90°, achieving the effect of passive medicine bottle replacement, reducing mistakes made by medical staff and increasing their attention.

[0033] For example, in the operating room, patients undergoing surgery generally need to be connected to nutrient solution to ensure their nutritional needs during the operation. When the first bag of nutrient solution is used up, medical staff do not need to manually replace it with the next bag of nutrient solution. This also ensures that there is no need for more nutrient solution during the bag change process.

[0034] See also Fig.11The present invention provides a technical solution: in this embodiment, a pulley with a self-locking function is provided at the bottom end of the base frame 1, a telescopic cylinder 33 is fixedly installed in the base frame 1, the telescopic cylinder 33 is fixedly connected to the telescopic column 2, and a controller 34 is fixedly installed on the outer side of the base frame 1, and the controller 34 controls the telescopic cylinder 33 to adjust the height of the infusion stand.

[0035] The telescopic cylinder 33 is controlled by the controller 34. When the telescopic cylinder 33 is extended, the telescopic column 2 is driven to rise, thereby adjusting the height of the infusion stand. When the controller 34 adjusts the height of the infusion stand, the required height of the infusion stand can be adjusted according to actual usage.

[0036] The working principle of this embodiment is as follows: the medicine bottle will make the hook 14 located at the bottom, so that the first extrusion spring 18 is in a stretched state. As the medicine in the medicine bottle is used, the weight of the medicine bottle begins to gradually decrease, and the first extrusion spring 18 will slowly rise, that is, the hook 14 will slowly rise. When the hook 14 rises, it will drive the first gear column 15 to move up, and the first gear column 15 is meshed and connected with the first rotating gear 17. In this way, the first gear column 15 will drive the second gear column 16 to move down through the first rotating gear 17, and will squeeze the second extrusion spring 19. When the second gear column 16 moves down, the piston plate 20 will move down in the sliding box 13 until the piston plate 20 and the contact block 21 contact each other, that is, all the medicine in the medicine bottle has been used up. When the piston plate 20 contacts the contact block 21, the signal generator will emit a signal, and the signal receiver on the motor 24 will The signal is received and the motor 24 is turned on. When the motor 24 is working, the top plate 3 is driven to rotate through the push plate 29, the third gear column 28, the second gear ring 26, the rotating column 25, the second rotating gear 27, the first gear ring 22 and the connecting rod 9. Each time the motor 24 is working, the top plate 3 rotates by 90°, and the sliding box 13 will also slide on the first fixed frame 4. When the top plate 3 rotates by 90°, the sliding plate 30 will be driven by the second medicine tube 8 to rotate 90° on the second fixed frame 5 at the same time. In this way, the next second medicine tube 8 will be reconnected with the connecting cavity 31, so that there is always medicine flowing into the first medicine tube 7, so that there is no need to manually replace the medicine bottle. After the medicine in the previous medicine bottle is used up, the next medicine bottle will be passively rotated 90°, so as to achieve the effect of passively changing the medicine bottle, reduce the mistakes of medical staff, and increase the attention of medical staff.

[0037] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
